They are not mirrored. They (and dentries and superblock) are literally
the same. mount --bind results in a new vfsmount that does (as any vfsmount)
refer to a subtree of some fs. In this case - preexisting subtree.
Mount tree consists of vfsmounts; there's nothing that would prohibit
several vfsmounts refering to the subtrees of the same dentry tree/same
(sub)tree/etc.
Al, carefully not saying what he really thinks of inotify; completely unfit
for repeating in public...
